Products Description
PP material is polypropylene, polypropylene is non-toxic, odorless, tasteless milky white high crystalline polymer, density is
only 0.90 - 0.91g /cm3, is one of the lightest varieties of all plastics. It is particularly stable to water, water absorption
rate is only 0.01%, molecular weight is about 81 thousand 150 thousand. Good molding, but because of the shrinkage rate (1% -2.5%). Thick wall products easy to sag, for some of the higher dimensional precision parts, it is difficult to meet the
requirements, good surface gloss.
